Supra Ply 3.4S Loudspeaker Cables


SKU: N/A Categories: ,


The radiation from unshielded loudspeaker cables is often stronger than that from ordinary mains cables. Supra screened loudspeaker cables radiate less interference to low level circuits, inputs and interconnects. The shielding is also highly effective in rejecting high frequency interference by minimising aerial pick-up. The minimising of interference fields is recommended in all fixed installations with computers playing an increasing part in everyday life.

The screened Supra Ply 3.4S combines low inductance and tin plating with the shielding concept making it Supra’s top high-end loudspeaker cable for everyday budgets.

Supra Ply is a largesection, low resistance cable, overcoming skin effect & transient distortion, using pure tin plating. Tin melds to copper with-out any diodic barrier, and also protects the copper from common corrosions – ideal for outdoors & 12 volt. Most audiograde cables’ conductors are damaged by contamination, by plastic out-gassing, from the impure atmosphere, and liquid spills. Some are protected but only by a thin coating that will one day crack with use and age.

The shielded Ply 3.4S provides even better performance when this model’s added screen earth lead is connected to speaker minus terminal or to the earth terminal in a wall socket or mains distribution block. The Ply also works well as a bi-wire/bi-amp pair. I prefer this solution to the larger four conductor cables.

Divine Audio build’s high end speaker cable using the best parts available from Supra, Neotech, Furutech, Cardas and CMC. Our cables are hand built in the UK. We are upfront and honest about what goes into our products and believe we are offering the best value in cables available today.

Any configuration and length is available. There are too many options to offer online so please contact me to go over your requirements and get a price. I have demo cables available to try out and I encourage you to test them in your own system.
